TRU Quick Disconnect Products
Mating Durability Test Report
Objective
Test & characterize the mating durability of TRU Quick Disconnect Products (SQS, QRM, and QDS) over an extended
number of mating cycles to simulate the lifetime performance of TRU quick disconnect interface(s). The test will measure
and monitor the following parameters: VSWR, insertion loss, phase, and insertion / withdrawal force to determine their
impact on electrical/ mechanical performance.

Test Procedure:
• Baseline electrical / mechanical tests were performed on each of the sample assemblies:
o VSWR, Insertion Loss, Phase
o Insertion & Withdrawal Force
o Interface Dimensions, Visual Examination of Product
• Each sample was subjected to 2500 mating cycles.
o Note: a cycle consists of 1 complete electrical / mechanical mating onto its corresponding mating adapter
and 1 complete un-mating from its corresponding adapter.
• After every 250 cycles, all electrical / mechanical tests & inspections performed at baseline were repeated on each
sample. The test results were summarized and recorded per the following data:

Results / Conclusions:
TRU Quick-Disconnect Products meet / exceed 500 mating cycle rating, without any degradation to electrical /
mechanical performance parameters.
The Insertion / Withdrawal force of TRU Quick Disconnect Products stabilizes and remains fairly constant after
approximately 1000 cycles.
TRU Quick Disconnect Products will operate a minimum of 2500 mating cycles without any significant impact on
electrical performance parameters.
